The discussion focuses on designing a bouncing egg-drop container that incorporates springs while protecting a raw egg during a drop from 1.0 meters. Participants suggest using cushioning materials like bubble wrap and sponges to absorb shock and enhance protection. A key challenge is ensuring the container bounces effectively in a specific direction upon landing, with ideas proposed to surround the container with springs for better directional control. Suggestions include using coiled springs to dissipate energy and improve bounce efficiency. The requirement to use springs as a primary material remains a constraint for the design.

Hello! :smile:
Could you please help me with materials and design ideas for a bouncing "egg-drop" container?

I have to make a bouncing "egg-drop" container that must be made with springs.
Any materials (except liquid) may be used.
The container will be dropped from 1.0m to the floor and it must protect a raw egg while achieving the largest number of clear bounces.

I think that protecting the egg part is fairly easy. What I need would be good cushioning and shock absorbing materials such as bubble wrap, sponges, etc. The springs (which I must use as one of the materials for the container) would also help reduce the impact. However, I don't know what kind of design would make the container to bounce most effectively. :confused:

The really difficult part is making it bounce in a same direction on a specific, small area of surface (where it is dropped on at first, not boucing off to other random areas)... :rolleyes:

Please help! I would great appreciate any advice or ideas. :wink:

does it absolutely have to be a "spring" or can you use some other material that makes the container bounce? i could think of ways to get it to bounce much more efficiently if you can use other materials

as far as helping with the directional problem, surround your container with springs so that it will bounce no matter which way it lands
 
How about a simple coiled spring, like a spring powered device winding, that surrounds a central egg container.

It should dissipate energy from any direction along the plane provided its dropped perpendicular to the coil axis.

Yes. Unfortunately, springs must be used as one of the materials for the container. :(

So, I would just need to attatch many springs around the container...
Thank you for your nice idea! :)

I really like your idea, but it is difficult for me to find a spring that big... :blushing: Thanks a lot, anyway! :)
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
